Natural Whetstone I don't know the details, but this is a natural whetstone. A carpenter who worked for 30 years used it, so I'm sure it's genuine, but I don't know how to judge it, so please judge from the images. You can use it or display it. Please judge the dimensions from the images. The price is what the carpenter said it would cost, or maybe a little more. #diy #DIY #chisel #chisel #chisel #setofchisels #setofchisels #carpenter #carpentrytools #tools #collection #blades #blade #chisel #setofchisels #chisel #tools #plane #plane #chisel #tools #plane #Kengo Usuzui #Tomoura #Shuji Kogata #sunpachi #sunroku #sunyon #sun #bu #traditionalcrafts #shave #old #new #used #readytouse #motsukuri #whetstone #naturalwhetstone #suita #akarenge #renge #naturalstone
